The swallowtail family of butterflies are my favorite.Their large wings, graceful shape, and colorful markings lure me into the garden. The butterflies are lured into the garden by various larval plants, each specific to their species.The eastern black swallowtail favors parsley, dill or fennel as its host plant and we have had caterpillars on all three.A few years ago the Tripps from Windy Hill Farm gave me some bronze fennel plants from their garden. They are very sturdy plants which reach 3 feet in height.  Probably due to their prominance in the garden,  I now find most of the black swallowtails...
